Science & Technology Q&A for Kids (and others) [July 30, 2021]

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa Questions include: Is there a reason why math has an order of operations, or is it just "because we decided on that"? - What does a day in the life of a scientist look like? - ​What is your opinion about reproducible research? - Stephen, I loved your conversation with Greg Chaitin!!! You made questions that reminded me to the questions that we ask you. Please make some podcast episodes where you have guests to whom you ask questions! - ​Will teleportation ever be possible, even if only for, say, a photon stream? If so could a probe sent into a black hole be able to transmit back images across the event horizon using this technique?
